摘要:
A series of 7-azaindolic ligands bearing a methoxy group and a N-acetyl chain as melatoninergic pharmacophores were synthesized and their binding affinities towards MT1 and MT2 receptors were evaluated. Compounds 7a-c and 12 (cyclohexyl ring connected at C-2 and C-3 position) appears as important melatonin MT2 and MT1 receptors agonists. On the other hand, the presence of basic groups (amines) at position C-3 was detrimental to the melatoninergic affinities. (C) 2011 Elsevier Ltd. All rights reserved.
